Methodological issues in conducting yoga- and meditation-based research: A narrative review and research implications
Abstract
Yoga and meditation-based interventions have been extensively utilized in the field of contemporary complementary and alternative medicine for various physical and mental health conditions. Ongoing COVID-19 pandemic has rekindled the interest of researchers in yoga and meditation for its preventive and therapeutic utilities. However, the available literature in this area has several methodological concerns, limiting formers’ clinical utility. A comprehensive literature on this topic would stimulate researchers and guide them to conduct research on this topic with robust methodologies. The current review highlights the methodological issues with the yoga and meditation-based Research (henceforth, MBR), discusses some of the contentious issues, and provides future directions. The PubMed, Medline, and google scholar databases were searched to screen records dealing with the methodological issues on MBR. The search yielded 299 records, upon screening, only 24 articles were found suitable for the current study. Common methodological issues with MBR: lack of the consensus definitions of the yoga and meditations, interventions lacking theoretical framework of meditation; inadequate description of the study design; difficulty with participants recruitment, setting up the control groups, and blinding; difficulty in assessing the baseline characteristics of the participants, and validity issues with the outcome measures. A few research, however, have also highlighted the potential measures to overcome these methodological challenges. Yoga and meditation-based interventions are promising for several health conditions. However, literature suffers from considerable methodological issues, thus, limiting its utility in modern clinical practice. The study findings can stimulate and guide future research on this topic.
